RHEL7.0用CentOS7.0在线yum源

woyoudn

　　1、首先查看RHEL7.0系统本身所安装的那些yum 软件包：
[root@max ~]# rpm -qa | grep yum
yum-utils-1.1.31-24.el7.noarch
yum-langpacks-0.4.2-3.el7.noarch
yum-metadata-parser-1.1.4-10.el7.x86_64
yum-rhn-plugin-2.0.1-4.el7.noarch
PackageKit-yum-0.8.9-11.el7.x86_64
yum-3.4.3-118.el7.noarch
2、卸载这些软件包：
[root@max ~]# rpm -e yum-3.4.3-118.el7.noarch --nodeps
[root@max ~]# rpm -e yum-utils-1.1.31-24.el7.noarch --nodeps
[root@max ~]# rpm -e yum-rhn-plugin-2.0.1-4.el7.noarch --nodeps
[root@max ~]# rpm -e yum-metadata-parser-1.1.4-10.el7.x86_64 --nodeps
[root@max ~]# rpm -e yum-langpacks-0.4.2-3.el7.noarch --nodeps
[root@max ~]# rpm -e PackageKit-yum-0.8.9-11.el7.x86_64 --nodeps
[root@max ~]# rpm -e python-urlgrabber-3.10-4.el7.noarch.rpm   【依赖关系】
3、保证本机电脑能上网；
[root@max ~]# ping www.baidu.co
PING www.a.shifen.com (61.135.169.121) 56(84) bytes of data.
64 bytes from 61.135.169.121: icmp_seq=1 ttl=53 time=31.8 ms

http://mirrors.163.com/centos/7/os/x86_64/Packages/python-urlgrabber-3.10-8.el7.noarch.rpm7、安装软件包：
[root@max ~]# ls
python-urlgrabber-3.10-8.el7.noarch.rpm
yum-3.4.3-132.el7.centos.0.1.noarch.rpm
yum-metadata-parser-1.1.4-10.el7.x86_64.rpm

[root@max ~]# rpm -ivh python-urlgrabber-3.10-8.el7.noarch.rpm
[root@max ~]# rpm -ivh yum-*
8、新建repo 配置文件；
[root@max ~]# vim /etc/yum.repos.d/CentOS-Base.repo
#CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#
#
[base]
name=CentOS-$7 - Base - 163.com
#mirrorlist=http://mirrorlist.centos.org/?release=$7&arch=$basearch&repo=os
baseurl=http://mirrors.163.com/centos/7/os/$basearch/
